-LRB- CNN -RRB- -- Jason Dinant has the opposite problem of most Americans -- he has flat abs .

Jason Dinant 's New Year 's resolution is to shape up his abs from flat to muscular .

Standing 6-feet , Dinant has a beanpole leanness many Americans covet . The 27-year-old 's ribs protrude from his chest , but he has some fat collecting in his stomach .

`` I do n't have that much body fat , but it tends to stick right here in my stomach , '' he said pinching his belly .

`` My goal is to get a six-pack by summer , '' Dinant declared in a video he submitted to iReport.com .

Dinant often peels off his shirt and gives what he calls `` the naked truth about today 's news '' in Web videos he posts on his blog called `` Naked Boy News . '' Watch Dinant 's video .

`` I give reports without a shirt on , so I should have the best body , '' he said . `` Who wants to see a guy with skinny arms and no abs ? ''

CNNhealth.com recently asked viewers to talk about their New Year 's resolutions on iReport.com and to upload photos and videos during their journey to change . Share your story with iReport.com .

Dinant works in sales during the day and has a night job as an emcee at a Las Vegas , Nevada , night club , where he is surrounded by toned and fit dancers .

`` There are go-go boys and girls with killer stomachs , '' Dinant said . `` I get up on the stage , I do n't take my shirt off . I 'm nervous about my stomach . ''

He does n't mind going topless on his videos , but he gets self-conscious in person .

With his high school reunion fast approaching this summer , Dinant wants to tone up in the next six months and develop chiseled abs like Shemar Moore of TV 's `` Criminal Minds '' or Ty Pennington , host of `` Extreme Makeover : Home Edition . ''

Until recently , the extent of Dinant 's exercise has been walking up the stairs and parking his car far away from stores .

Now Dinant works out four times a week in a gym inside his apartment complex , cycling on a stationary bike , using weights on his upper body and doing 500 sit-ups a day .

A televised Britney Spears interview gave him the idea for the sit-ups routine .

`` I heard her saying that she 'd do 1,000 sit-ups a day , '' Dinant said . `` She had amazing abs . If she can do it , I can do it . ''

But the sit-ups get old , Dinant said .

To distract himself , he watches TV shows such as `` The Bachelor '' while crunching , or he thinks of games -LRB- `` Every time you do sit-up , you name an Osmond child '' -RRB- to pass the time .

Contrary to popular opinion , traditional sit-ups are n't the most effective way to get a six-pack , said Robert Dothard , a personal trainer based in Atlanta , Georgia .

`` Crunches are great to flatten the stomach , '' he said . `` For men , we have to put abs under weight resistance to make them stick out . ''

The ab segments that make up a six-pack exist under layers of fat and skin . To make the six-pack more pronounced , a person has to exercise and lose the excess fat so those muscles are visible . That comes through cardio exercises .

To make those stomach muscles bigger , `` abs have to be put under resistance , '' Dothard said . Those muscles need weight training to become bigger and more prominent .

He recommended doing sit-ups on a stability ball while holding a medicine ball over the head and crunching . Using a resistance band anchored around a stationary bar while performing side-to-side twists also creates resistance , he said . Dothard demonstrated these moves on a video . Watch Dothard 's fitness demonstrations . ''

Someone with a svelte frame such as Dinant 's may not look as if he or she needs to exercise , but appearances can be deceiving .

`` People can be lean , but still carry a lot of fat , '' Dothard said .

Research suggests that it 's wise for even lean people to lose the belly fat . Even with a normal body mass index , people can carry extra weight in their stomachs , which increases the risk for cardiovascular disease . Those with belly fat have a higher risk of dying compared to their peers without it .

But , Dinant 's reasons for wanting a taut stomach remain purely aesthetic .

`` I have my 10-year high school reunion coming up , '' Dinant said . `` I want to go back and be like , ` Bam . Look at me . ' ''
